I said during my presentation that Canada was a bit late. Sometimes there are advantages to being a bit late, because we can build on what has been done elsewhere. Quebec's Act Respecting Labour Standards contains elements concerning the definition. Federal legislation also contains elements. For example, the Charter contains prohibited grounds of discrimination such as race, sex, and so on.
It is important to look at what's in the labour laws. A sentence saying what is not harassment can even be included. For example, the exercise of the right to manage, when done well, is not harassment.
I would like to add that if, in Saskatchewan, it was found that half of the complaints were unfounded, that does not mean there is no problem.
